The cleats 5 acquire a strong hold on the ground and are impelling or driving cleats, the function of the circumferential cleats 9 being to prevent lateral skidding or slipping. Owing to the presence of the openings 2, the wheel will obtain a hold upon the earth. Any earth that passes in toward the center of rotation of the wheel will be caught by i the combined spokes and mud guards 20, and will be deflected laterally out of the wheel, in a way which will be understood readily when Figure 2 of the drawings is noted. The wings 33 prevent the earth from moving circumferentially within the wheel, and aid in directing the earth out of the wheel and toward the side thereof.

In the modification shown in Figure 6 of the drawings, parts hereinbefore described have been designated by numerals previously used, with the sutiix a. The axle 1O is received within the hub 14:. The body forming members 20 are engaged between the ring 17 and through the tongue 26*. The ring 19 of Figure 2 is replaced by a sprocket wheel 44. The spokes 40 have extensions 43 which extend into the hub la, in a direction parallel to the axle 10 Securing elements 45 extend through the sprocket wheel 44;, through the inner ends of the spokes 40 and into the hub 14.

This invention provides a means whereby asprocket wheel may be mounted in place, should it be desired to drive the tractor wheel by means of a sprocket chain. Owing to the length of the hub 14%, the spokes 4O slant inwardly in Figure 6, instead of outwardly as in Figure 2.

\Vhat is claimed is 1. A wheel comprising a tread, a hub, a plurality of approximately triangular bodyforming members having extensions, the extension of one body-forming member overlapping the next-adjoining body-forming member, means for securing said extensions to the adjoining aforesaid members to form a conical body, that edge of each body-forming member which is opposite to the extension being provided with a wing extended from one side of the wheel toward the other, the wing being supplied along one edge with flange extended transversely of the wheel in engagement with the innersurface of the tread, means for securing the win to the tread, and means for securing the body to the hub.

2. A wheel comprising a tread, a hub, a plurality of approximately triangular bodyforming members having extensions, the extension of one body-forming member overlapping the next-a'djoining body-forming member, means for securing said extensions to the adjoining aforesaid members to form a conical body, that edge of each body-forming member which is opposite to the extension being provided with a wing extended from one side of the wheel toward the other, the wing being supplied along one edge with a flange extended transversely of the wheel in engagement with the inner surface of the tread, the flange having a lip, the tread having an inwardly-extended side piece to which the lip is secured, and means for attaching the body to the hub.

In testimony that I claim the foregoing as 'my own, I have hereto aflixed my signature.
